I hit a rock in Idaho and bent both wheels. To straighten them heat is applied which will ruin the original finish. I also believe when they scan for cracks or micro fissures, they may destroy original finishes. Anyway, the wheel shop is set up to do powder coating, too. I had my '03 wheels colored to match the engine cases. Straightening was $100/wheel, powder coating an additional $50/wheel. They put a tough clear coat of some kind over the powder coat and that finish has a couple of drip flaws, but otherwise the finish is brilliant and has held up very well. But always be aware of ham-fisted tire change guys at the shops - they'll gouge and scrape the hell out of anything.
